ABSTRACT
Holong Erixon Manurung “The Effectifity Suspension Baculovirus oryctes And Metarhizium anisopliae (Metch.) Sorokin of Brontispa longissima Gestro.
(Coleoptera : Chrysomelidae) in Laboratory”, under guidance of Ir. Syahrial Oemry and Ir. Fatimah Zahara. The objectives of this research were to
study the effectifity Suspension Baculovirus oryctes and Metarhizium anisopliae (Metch.) Sorokin of Brontispa longissima Gestro.
(Coleoptera : Chrysomelidae) in Laboratory.
The research was held at the laboratory of pest and plant disease, Agroecotechnology Program Study, Agricultural Faculty, University of Sumatera Utara, Medan on April to Mei 2014. This methode used Randomized
Complete Design (RAL) of non Factorial that consist of 7 treatments and 4 replications.The tested treatment were: 1.T0 : (control) aplication 500 mL
aquadest + 5 adult + young coconut leaf 2.T1 : suspension 40 ml B. oryctes/500 mL aquadest +5 adult + young coconut leaf 3. T2 : suspension 50 ml B. oryctes / 500 mL aquadest + 5 adult + young coconut leaf 4. T3 : suspension 60 ml B. oryctes / 500 mL aquadest + 5 adult + young coconut leaf 5. T4 : suspension 40 gr M. anisopliae /500 mL aquadest + 5 adult + young coconut leaf 6. T5: suspension 50 gr M. anisopliae / 500 mL aquadest + 5 adult + young coconut leaf 7. T6 : suspensi 60 gr M. anisopliae / 500 mL aquadest+5 adult + young coconut leaf. Parameters observed were percentage of mortality and effect of infection.
The results showed that the highest percentage of mortality on T6 was about 95,00% and the lowest on T1 was about 60%.
Key words: Effectifity, B. oryctes, M. anisopliae, Brontispa longissima Gestro,

Gestro. (Coleoptera :Chrysomelidae) Di Laboratorium” di bawah bimbingan Ir.
Syahrial Oemry, M.S dan Ir. Fatimah Zahara. Penelitian ini bertujuan untuk mengetahui uji efektivitas suspensi Baculovirus oryctes Dan Metarhizium anisopliae (Metch.) Sorokin Terhadap Brontispa longssima Gestro. (Coleoptera :Chrysomelidae) Di Laboratorium.
Penelitian ini dilaksanakan di Laboratorium Hama dan Penyakit Program Studi Agroekoteknologi Fakultas Pertanian Universitas Sumatera Utara, Medan pada Bulan April-Mei 2014. Metode yang digunakan adalah Rancangan Acak Lengkap (RAL) non Faktorial yang terdiri dari 7 perlakuan dan 4 ulangan. Perlakuan yang diuji yaitu :1. T0 : (kontrol) aplikasi air /500 mL air + 5 Imago + Daun janur muda 2. T1 : suspensi 40 ml B. oryctes /500 mL air + 5 Imago + Daun janur muda 3. T2 : suspensi 50 ml B. oryctes / 500 mL air + 5 Imago + Daun janur muda 4. T3 : suspensi 60 ml B. oryctes / 500 mL air + 5 Imago + Daun janur muda 5. T4 : suspensi 40 gr M. anisopliae / 500 mL air + 5 Imago + Daun janur muda 6. T5 : suspensi 50 gr M. anisopliae / 500 mL air + 5 Imago + Daun janur muda 7. T6 :suspensi 60 gr M. anisopliae / 500 mL air + 5 Imago + Daun janur muda.
Parameter yang diamati meliputi: persentase mortalitas, gejala infeksi.
Hasil penelitian menunjukkan bahwa persentase mortalitas tertinggi terdapat pada perlakuan T6 yaitu sebesar 95.% dan yang terendah pada perlakuan T1 sebesar 60%.
Kata Kunci : Efektivitas, B. oryctes, M. anisopliae, Brontispa longissima Gestro.
